Hazureta Kubiwa wo Suteru Toki

Is it so wrong for two abandoned souls to fall in love? Kuroda catches his boyfriend cheating and gets dumped on the spot, only to discover another man, Shirato, was also dumped. Out of pity, Kuroda takes the crying Shirato home, and their shared loneliness leads to a one-night stand. But what should have been a one-time mistake turns into something deeper, as Kuroda finds a strange comfort in being embraced by Shirato. But how can he confess his growing feelings now?
